Ein gattungsgemäßes Wandelement für eine Lärmschutzwand ist aus der KR 101830146 B1 bekannt. Ein vorderes, der Schallseite zugewandtes Blech ist dabei gebogen ausgebildet, das heißt es erstreckt sich von oben ausgehend nach vorne aus der Ebene der Schallschutzwand heraus und wird dann in einem Winkel von nahezu 90° wieder zur Schallschutzwand zurückgeführt. An dieser Unterseite des vorderen Blechs, das zumindest an der Unterseite als Lochblech ausgebildet ist, ist dann ein nach unten gerichtetes LED-Modul befestigt, das auf ein darunter gerichtetes, in ähnlicher Form gebogenes Blech abstrahlt.A generic wall element for a noise barrier is from the KR 101830146 B1 known. A front sheet metal facing the sound side is curved, that is, it extends from the top and extends forward out of the plane of the soundproof wall and is then returned to the soundproof wall at an angle of almost 90 °. On this underside of the front sheet, which is designed at least on the underside as a perforated sheet, a downward-directed LED module is then attached, which emits onto a sheet that is directed below and is bent in a similar shape.

Aus der JP H05-3318 U ist eine weitere Schallschutzwand bekannt, an der eine Lampe außen an der Schallschutzwand angebracht ist.From the JP H05-3318 U Another soundproof wall is known, on which a lamp is attached to the outside of the soundproof wall.

Die CN 106351137 A zeigt eine weitere Schallschutzwand, an deren verkehrszugewandter Seite mehrere Funktionselemente angeordnet sind. Dort ist beispielsweise eine Lampe zu Beleuchtungszwecken angeordnet. Weiterhin ist dort ein Radarsensor zur Geschwindigkeitserfassung vorgesehen.The CN 106351137 A shows a further soundproofing wall, on the traffic-facing side of which several functional elements are arranged. A lamp for lighting purposes is arranged there, for example. A radar sensor for speed detection is also provided there.

Ein Wandelement für eine Lärmschutzwand, dessen Frontblech ein lackiertes Aluminium-Lochblech ist, ist in der DE 30 09 082 A1 beschrieben.A wall element for a noise protection wall, the front plate of which is a painted aluminum perforated plate, is in the DE 30 09 082 A1 described.

Ein gattungsgemäßes Wandelement für eine Lärmschutzwand ist aus der DE 10 2017 008 181 A1 bekannt. Das dort beschriebene Lärmschutzelement, das ein flächiges Abdeckelement mit Schallöffnungen, insbesondere ein Streckmetall oder ein Lochblech aufweist.A generic wall element for a noise barrier is from the DE 10 2017 008 181 A1 known. The noise protection element described there, which has a flat cover element with sound openings, in particular an expanded metal or a perforated plate.

Weitere Details des konstruktiven Aufbaus von derartigen Wandelementen sind beispielsweise in der EP 2 607 554 B1 beschrieben. Im Inneren des Wandelements sind insbesondere auch Dämpfungselemente vorgesehen und aufgenommen, die durch das Lochblech eintretenden Schall aufnehmen und absorbieren.Further details of the structural design of such wall elements are, for example, in the EP 2 607 554 B1 described. In the interior of the wall element, in particular damping elements are provided and received, which absorb and absorb sound entering through the perforated plate.

Der Erfindung liegt die Aufgabe zugrunde, ein Wandelement der eingangs genannten Art weiterzuentwickeln und einen besonderen Schutz für die Lichtquelle zu schaffen.The invention has for its object to further develop a wall element of the type mentioned and to provide special protection for the light source.

Die Lösung dieser Aufgabe erfolgt mit einem Wandelement mit den Merkmalen das Patentanspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved with a wall element with the features of claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Bei einem Wandelement für eine Lärmschutzwand, wobei das Wandelement zwei gegenüberliegende Flächen aufweist, von denen eine Seite potentiellen Schallquellen zugewandt ist und diese Seite zumindest ein Lochblech und eine Lichtquelle aufweist, ist erfindungswesentlich vorgesehen, dass die der potentiellen Schaltquelle zugewandte Seite des Wandelements überwiegend mit dem Lochblech verkleidet ist, dass die mindestens eine Lichtquelle hinter dem Lochblech innerhalb des Wandelements angeordnet ist, so dass das Licht der Lichtquelle durch die Löcher des Lochblechs nach außen abgegeben werden kann. Auf diese Weise kann das Wandelement durch die Aufnahme von mindestens einer Lichtquelle um eine zusätzliche Beleuchtungsfunktion und weitergehend sogar um Informationssysteme erweitert werden, die durch die Beleuchtung erreicht werden. Die Verwendung eines Lochblechs, wobei der Begriff weitgehend als metallisches Abschlusselement mit Durchbrüchen zu verstehen ist, insbesondere in der typischen Ausgestaltung eines Blechs mit kreisförmigen Löchern, erfolgt bevorzugt auf der gesamten Seite, die der Schallquelle zugewandt ist, bevorzugt auf mehr als 90 % dieser Fläche. Hinter dem Lochblech ist ein schalldämpfendes Material und/oder ein schalldämpfender Körper angeordnet, der die durch die Löcher oder Ausnehmungen in das Lochblech eindringenden Schallwellen aufnimmt und absorbiert. Gleichzeitig besteht bei Verwendung eines solchen Lochblechs die Möglichkeit, hinter dem Lochblech Lichtquellen anzuordnen. Diese können das Licht durch die Löcher oder Ausnehmungen nach außen abgeben. Das Licht wird derart durch die Löcher nach außen abgegeben, dass dieses im Wesentlichen rechtwinklig von dem Wandelement nach außen wegstrahlt und/oder von dort zu sehen ist. Ein Betrachter kann also durch die Löcher des Lochblechs die dahinterliegenden Lichtquellen sehen. Gleichzeitig wird durch das Lochblech ein Schutz der im Inneren des Wandelements angeordneten Elemente, also insbesondere des Dämmelements und auch der Lichtquellen gegen Witterungseinflüsse und auch gegen unbefugten Zugriff erreicht.In the case of a wall element for a noise protection wall, the wall element having two opposite surfaces, one side of which faces potential sound sources and this side has at least one perforated plate and one light source, it is essential to the invention that the side of the wall element facing the potential switching source predominantly coincides with the Perforated sheet is clad so that the at least one light source is arranged behind the perforated sheet within the wall element, so that the light of the light source can be emitted to the outside through the holes in the perforated sheet. In this way, the wall element can be expanded by the inclusion of at least one light source by an additional lighting function and, moreover, even by information systems that are achieved by the lighting. The use of a perforated plate, the term being used largely as a metallic end element with openings is to be understood, in particular in the typical configuration of a sheet with circular holes, preferably takes place on the entire side facing the sound source, preferably on more than 90% of this area. A sound-absorbing material and / or a sound-absorbing body is arranged behind the perforated plate, which absorbs and absorbs the sound waves penetrating into the perforated plate through the holes or recesses. At the same time, when using such a perforated plate, there is the possibility of arranging light sources behind the perforated plate. These can emit the light through the holes or recesses to the outside. The light is emitted to the outside through the holes in such a way that it radiates outward at right angles from the wall element and / or can be seen from there. A viewer can see the light sources behind through the holes in the perforated plate. At the same time, the perforated plate provides protection for the elements arranged in the interior of the wall element, in particular for the insulation element and also for the light sources, against weather influences and also against unauthorized access.

In einer besonders bevorzugten Ausführungsform ist die Lichtquelle eine LED. Die Lichtquelle ist dabei bevorzugt aus einer Vielzahl von LED's zusammengesetzt. Auch andere Lichtquellen sind denkbar, insbesondere alle Arten von Lichtquellen, die im Bereich der Straßenbeleuchtung zum Einsatz kommen.In a particularly preferred embodiment, the light source is an LED. The light source is preferably composed of a large number of LEDs. Other light sources are also conceivable, in particular all types of light sources that are used in the field of street lighting.

In einer besonders bevorzugten Ausführungsform hat die Lichtquelle eine horizontale Erstreckung über mindestens 50 % der Länge des Wandelements. Besonders bevorzugt beträgt die horizontale Erstreckung mindestens 90 % der Länge des Wandelements und besonders bevorzugt 100 % der Länge des Wandelements. Aus technischen Gründen können schmale Randstreifen davon ausgenommen sein.In a particularly preferred embodiment, the light source has a horizontal extension over at least 50% of the length of the wall element. The horizontal extent is particularly preferably at least 90% of the length of the wall element and particularly preferably 100% of the length of the wall element. For technical reasons, narrow edge strips can be excluded.

In einer anderen besonders bevorzugten Ausgestaltung der Erfindung weist das Wandelement mindestens zwei übereinander angeordnete, sich horizontal erstreckende Lichtquellen auf, die beabstandet zueinander sind. Das bedeutet insbesondere, dass zwischen den beiden Lichtquellen ein nicht beleuchteter Streifen verbleibt, so dass die beiden Lichtquellen als getrennte Lichtstreifen wahrgenommen werden.In another particularly preferred embodiment of the invention, the wall element has at least two horizontally arranged one above the other extending light sources that are spaced apart. This means in particular that an unilluminated strip remains between the two light sources, so that the two light sources are perceived as separate light strips.

In einer anderen, besonders bevorzugten Ausgestaltung der Erfindung ist in dem Wandelement eine großflächige Lichtquelle angeordnet, insbesondere eine Lichtquelle, die aus einer Vielzahl von LED-Punkten besteht, und über die direkt oder in Lauschrift oder mit von oben nach unten oder von unten nach oben durchlaufenden Zeichen Informationen dargestellt werden können. Die einzelnen LED Punkte sind dazu vorgesehen und ausgelegt, einzeln angesteuert zu werden. Auf diese Weise können Nachrichten und Botschaften erstellt werden.In another, particularly preferred embodiment of the invention, a large-area light source is arranged in the wall element, in particular a light source which consists of a multiplicity of LED points, and via which directly or in text or with from top to bottom or from bottom to top continuous characters information can be displayed. The individual LED points are intended and designed to be controlled individually. In this way, messages and messages can be created.

In einer anderen bevorzugten Ausgestaltung der Erfindung weist das Wandelement Lichtquellen für mindestens drei verschiedene Farben auf. Dies kann entweder so gestaltet sein, dass die Lichtquellen, insbesondere LED's, in drei oder mehr Farbtönen vorliegen oder es können Lichtquellen vorhanden sein, deren Farbe veränderbar ist. Entweder wird dies durch die Art der Lichtquelle selbst oder durch Vorschalten eines entsprechenden Filters erreicht. Auch die Verwendung von zwei Farben ist im Einzelfall eine günstige und bevorzugte Ausgestaltung. In einer besonders bevorzugten Ausgestaltung werden jedoch insbesondere die drei Ampelfarben grün, gelb und rot zur Anwendung kommen, um Verkehrsteilnehmern, die sich entlang der Lärmschutzwand bewegen, Informationen zu übermitteln.In another preferred embodiment of the invention, the wall element has light sources for at least three different colors. This can either be designed in such a way that the light sources, in particular LEDs, are available in three or more colors or there can be light sources whose color can be changed. This is achieved either by the type of light source itself or by connecting an appropriate filter. The use of two colors is also a favorable and preferred embodiment in individual cases. In a particularly preferred embodiment, however, the three traffic light colors green, yellow and red will be used in particular to transmit information to road users moving along the noise barrier.

In einer anderen Weiterbildung der Erfindung ist dem Wandelement eine Steuereinrichtung zugeordnet, insbesondere in dem Wandelement vorgesehen, die die Lichtquelle des Wandelements gemeinsam und/oder in Abhängigkeit mit oder von den Lichtquellen anderer Wandelemente steuert. Dadurch wird eine Informationsvermittlung über die Lichtquellen des Wandelements erreicht, die in Anpassung an typische Geschwindigkeiten von Verkehrsteilnehmern und/oder in Anpassung an individuelle Geschwindigkeiten einzelner Verkehrsteilnehmer auf benachbarte Wandelemente übertragen werden kann, so dass die Wahrnehmbarkeit verbessert wird. In diesem Zusammenhang stellt es eine besonders bevorzugte Weiterentwicklung der Erfindung dar, dass dem Wandelement eine Geschwindigkeitsmesseinrichtung zur Messung der Geschwindigkeit von Fahrzeugen im Bereich des Wandelements zugeordnet ist. Diese Geschwindigkeitsmesseinrichtung kann in dem Wandelement selbst integriert sein oder kann räumlich getrennt von dem Wandelement sein und mit den Lichtquellen des Wandelements nur in Datenverbindung stehen. Dadurch ist es möglich, die Lichtquellen, insbesondere die farbige Zuordnung der Lichtquellen, in Abhängigkeit von der Geschwindigkeit von Fahrzeugen im Bereich des Wandelements zu steuern. Alternativ kann eine gleichbleibende Information parallel zum Fahrzeug mitgeführt werden.In another development of the invention, a control device is assigned to the wall element, in particular provided in the wall element, which controls the light source of the wall element jointly and / or in dependence on or from the light sources of other wall elements. This provides information about the light sources of the wall element, which in adaptation to typical speeds of Road users and / or in adaptation to individual speeds of individual road users can be transferred to adjacent wall elements, so that the perceptibility is improved. In this context, it is a particularly preferred further development of the invention that the wall element is assigned a speed measuring device for measuring the speed of vehicles in the area of the wall element. This speed measuring device can be integrated in the wall element itself or can be spatially separated from the wall element and only have a data connection with the light sources of the wall element. This makes it possible to control the light sources, in particular the color assignment of the light sources, as a function of the speed of vehicles in the area of the wall element. Alternatively, constant information can be carried parallel to the vehicle.

In einer besonders bevorzugten Ausgestaltung ist das Wandelement, insbesondere die Steuereinrichtung, die dem Wandelement zugeordnet ist, zur Einbindung in ein Verkehrsleitsystem vorgesehen und ausgelegt. Dadurch kann das gesamte Wandelement um vielfältige Funktionen erweitert und daher mit besonderem Vorteil genutzt werden.In a particularly preferred embodiment, the wall element, in particular the control device which is assigned to the wall element, is provided and designed for integration into a traffic control system. As a result, the entire wall element can be expanded to include a variety of functions and can therefore be used with particular advantage.

Ein anderer Aspekt der Erfindung betrifft die Bereitstellung einer Lärmschutzwand zur Verringerung von Schallimmissionen entlang von Verkehrswegen mit vertikal aufgestellten Pfosten und zwischen den Pfosten angeordneten Wandfeldern, die sich dadurch auszeichnen, dass jedes Wandfeld wenigstens ein, bevorzugt jedoch zwei, drei oder mehr Wandelemente der oben beschriebenen Art aufweist.Another aspect of the invention relates to the provision of a noise barrier for reducing noise emissions along traffic routes with vertically erected posts and wall panels arranged between the posts, which are characterized in that each wall panel has at least one, but preferably two, three or more, wall elements of those described above Type.

Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten bevorzugten Ausführungsbeispiels weiter erläutert. Im Einzelnen zeigen die schematischen Darstellungen in: und

Fig. 1:
einen erstes Ausführungsbeispiels der Erfindung;
Fig. 2.:
ein zweites Ausführungsbeispiel der Erfindung.
The invention is explained in more detail below on the basis of a preferred exemplary embodiment shown in the drawing. The schematic diagrams show in detail: and
Fig. 1:
a first embodiment of the invention;
Fig. 2 .:
a second embodiment of the invention.

In Figur 1 ist eine Lärmschutzwand 1 dargestellt, wobei in der Figur drei Pfosten 2 und insgesamt vier Wandfelder 3 dargestellt sind. Die Wandfelder 3 entsprechen in dieser Ausführungsform auch jeweils den Wandelementen 4, da in dieser Ausführungsform jedes Wandfeld 3 aus nur einem einzigen Wandelement 4 gebildet ist. Die Lärmschutzwand 1 ist hier entlang einer Straße mit einem beispielhaft dargestellten Kraftfahrzeug 12 dargestellt. Die von dem Straßenverkehr ausgehenden Lärmemmissionen sollen mit Hilfe der Lärmschutzwand gemindert werden. Straßenseitig weist die Lärmschutzwand dazu ein Lochblech 6, hier besonders bevorzugt ein gewelltes Lochblech, mit einer Vielzahl von Ausnehmungen 7 oder Löchern auf, durch die der Schall in die Wandelemente 4 eindringt und dort von entsprechend in den Wandelementen angeordneten Dämmmaterialien und/oder Dämmgeometrien aufgenommen und absorbiert wird. In jedem Wandelement 4 sind hier drei Lichtquellen 8, 9 und 10 angeordnet, wobei die Lichtquellen 8 und 9 sich jeweils horizontal über die gesamte Länge des Wandelements 4 erstrecken. Zwischen den Lichtquellen 8 und 9 verbleibt jeweils ein unbeleuchteter Zwischenraum 11, der die Lichtquellen 8 und 9 optisch trennt. Jedes Wandelement 4 weist an seiner Oberseite einen oberen Abschluss 5 auf, der hier als Rundblech zur Abweisung von Witterungseinflüssen und insgesamt auch zur statischen Stabilisierung der Wandelemente vorgesehen ist. Unterhalb dieses oberen Abschlusses 5 ist hier ebenfalls eine weitere Lichtquelle 10 angeordnet. Die Lichtquellen 8 und 9 sind hinter dem Lochblech angeordnet und dadurch in das Wandelement 4 integriert. Die Lichtquelle 10 ist innerhalb des oberen Abschlusses 5 angeordnet. Diese kann in Einzelfällen auch außerhalb, also vor dem Lochblech angeordnet sein. Dies ist insbesondere dann möglich, wenn ein Schutz durch den oberen Abschluss 5 gegeben ist. Bei den typischerweise und erfindungsgemäß hinter dem Lochblech angeordneten Lichtquellen erfolgt die Abstrahlung durch die Ausnehmungen 7 des Lochblechs 6 hindurch. Besonders günstig ist hier der Einsatz von LED's, da diese bei vergleichsweise geringem Energiebedarf eine hohe Lichtintensität haben.In Figure 1 A noise barrier 1 is shown, three posts 2 and a total of four wall sections 3 being shown in the figure. In this embodiment, the wall panels 3 also correspond to the wall elements 4, since in this embodiment each wall panel 3 is formed from only a single wall element 4. The noise barrier 1 is shown here along a road with a motor vehicle 12 shown as an example. The noise emissions from road traffic are to be reduced with the help of the noise barrier. On the street side, the noise barrier has a perforated plate 6, in this case particularly preferably a corrugated perforated plate, with a plurality of recesses 7 or holes through which the sound penetrates into the wall elements 4 and is picked up there by insulation materials and / or insulation geometries arranged in the wall elements and is absorbed. Three light sources 8, 9 and 10 are arranged in each wall element 4, the light sources 8 and 9 each extending horizontally over the entire length of the wall element 4. Between the light sources 8 and 9 there remains an unilluminated space 11, which optically separates the light sources 8 and 9. Each wall element 4 has an upper end 5 on its upper side, which is provided here as a round plate for rejecting weather influences and overall for the static stabilization of the wall elements. A further light source 10 is also arranged below this upper termination 5. The light sources 8 and 9 are arranged behind the perforated plate and thereby integrated into the wall element 4. The light source 10 is arranged within the upper termination 5. In individual cases, this can also be arranged outside the perforated plate. This is possible in particular if protection is provided by the upper end 5. In the case of the light sources typically and according to the invention arranged behind the perforated plate, the radiation takes place through the Recesses 7 of the perforated plate 6 through. The use of LEDs is particularly favorable here, since they have a high light intensity with a comparatively low energy requirement.

In Figur 2 ist wiederum eine Lärmschutzwand mit Pfosten 2 und zwischen den Pfosten 2 befindlichen Wandfeldern 3 dargestellt, wobei jedes Wandfeld 3 hiervon genau einem Wandelement 4 gebildet ist. Wie bereits bei der Ausführungsform in Figur 1 weisen die Wandelemente 4 auf der im Bild dargestellten Seite, die den Schallwellen, also dem Kraftfahrzeug 12 zugewandt ist, das Lochblech 6 auf. In dem in der Figur rechten Wandelement 4 sind insgesamt sechs Lichtquellen 13 bis 18 vorhanden. Diese sind hier als rote Lichtquellen dargestellt. Bevorzugt sind diese jedoch schaltbar und in andere Farben umschaltbar. Die Lichtquellen 13, 14 und 17,18 erstrecken sich jeweils über die gesamte bzw. nahezu gesamte Länge des Wandelements 4 und sind jeweils durch einen unbeleuchteten Zwischenraum 11 voneinander getrennt. Die Lichtquellen 15, 16 erstrecken sich nur über einen Teilbereich des Wandelements 4. In den beiden mittleren Wandfeldern sind Lichtquellen 19 bis 26 in der Farbe Gelb dargestellt. Die Lichtquellen 21, 22 erstrecken sich dabei wieder über die gesamte Länge eines Wandelements 4 während die übrigen Lichtquellen sich nur über Teilbereiche des Wandelements 4 erstrecken. Die Lichtquellen 23, 24 und 25, 26 sind in unterschiedlichen Höhen angeordnet und jeweils nur über einen Teilbereich des Wandelements ausgebildet. Die Länge der Lichtquellen 23, 24 einerseits und 25, 26 andererseits addieren sich jedoch zur Gesamtlänge des Wandelements 4. Zwischen den horizontalen Lichtquellen sind unbeleuchtete Zwischenräume 11. Diese Lichtquellen sind gelb. Im Wandelement ganz links sind Lichtquellen 27 bis 30, die grün sind. Über derartig farbige Lichtquellen und eine entsprechende Steuereinrichtung und die Einbindung in ein Verkehrsleitsystem lassen sich Informationen an den Fahrer des Kraftfahrzeuges 12 übertragen. Insbesondere kann durch die Farben ein Überschreiten einer Höchstgeschwindigkeit oder Richtgeschwindigkeit vermittelt werden. Bei zu schneller Fahrt besteht auch die Möglichkeit, die rot angesteuerten Lichtquellen, parallel mit dem Kraftfahrzeug 12 mitlaufen zu lassen und die entsprechenden roten Lichtquellen jeweils in dem Wandelement 4 zu aktivieren (oder entsprechend farblich umzuschalten) an denen sich das Kraftfahrzeug 12 befindet. Dazu muss in die Steuereinrichtung der Wandelemente eine Information zur Geschwindigkeit des Kraftfahrzeuges 12 eingespeist werden. Dies kann über eine eigene Messung der Geschwindigkeit des Kraftfahrzeugs mit einer entsprechenden Messvorrichtung erfolgen. Alternativ könnten auch Daten mit dem Kraftfahrzeug ausgetauscht werden.In Figure 2 a noise barrier with posts 2 and wall panels 3 located between the posts 2 is again shown, each wall panel 3 being formed by exactly one wall element 4. As already in the embodiment in Figure 1 the wall elements 4 have the perforated plate 6 on the side shown in the picture, which faces the sound waves, that is to say the motor vehicle 12. A total of six light sources 13 to 18 are present in the wall element 4 on the right in the figure. These are shown here as red light sources. However, these are preferably switchable and switchable to other colors. The light sources 13, 14 and 17, 18 each extend over the entire or almost entire length of the wall element 4 and are each separated from one another by an unilluminated intermediate space 11. The light sources 15, 16 only extend over a partial area of the wall element 4. In the two central wall fields, light sources 19 to 26 are shown in yellow. The light sources 21, 22 extend again over the entire length of a wall element 4, while the other light sources only extend over partial areas of the wall element 4. The light sources 23, 24 and 25, 26 are arranged at different heights and each formed only over a partial area of the wall element. However, the length of the light sources 23, 24 on the one hand and 25, 26 on the other hand add up to the total length of the wall element 4. Between the horizontal light sources there are unilluminated gaps 11. These light sources are yellow. In the wall element on the far left are light sources 27 to 30, which are green. Information of this kind can be transmitted to the driver of the motor vehicle 12 via such colored light sources and a corresponding control device and the integration into a traffic control system. In particular, the colors can convey an exceeding of a maximum speed or a guiding speed. If the journey is too fast, there is also the option of turning red controlled light sources to run in parallel with the motor vehicle 12 and to activate the corresponding red light sources in each case in the wall element 4 (or to switch accordingly in color) on which the motor vehicle 12 is located. For this purpose, information about the speed of the motor vehicle 12 must be fed into the control device of the wall elements. This can be done by measuring the speed of the motor vehicle with an appropriate measuring device. Alternatively, data could also be exchanged with the motor vehicle.

Alle in der vorstehenden Beschreibung und in den Ansprüchen genannten Merkmale sind in einer beliebigen Auswahl mit den Merkmalen des unabhängigen Anspruchs kombinierbar. Die Offenbarung der Erfindung ist somit nicht auf die beschriebenen bzw. beanspruchten Merkmalskombinationen beschränkt, vielmehr sind alle im Rahmen der Erfindung sinnvollen Merkmalskombinationen als offenbart zu betrachten.All features mentioned in the above description and in the claims can be combined in any selection with the features of the independent claim. The disclosure of the invention is thus not limited to the combinations of features described or claimed; rather, all combinations of features which make sense in the context of the invention are to be regarded as disclosed.
